01 / What We Fabricate
The Mechanical Platform Around the Process Tool
Semiconductor equipment combines precision modules, utilities, controls and service access inside a large mechanical system. We fabricate the external enclosure and structural platform to the OEM's controlled drawings, with special attention to weld distortion, interface datums, clean assembly and revision traceability.
External Enclosure Systems
Powder-coated or stainless panel sets with doors, removable covers, windows, vents and controlled cosmetic gaps.
Internal Trays and Supports
Stainless drip trays, cable paths, brackets, rails and equipment mounts prepared for OEM integration.
Documented Mechanical Assembly
Hardware installation, fit checks, inspection records and configuration-controlled packout by tool variant.
Our scope: the mechanical enclosure, frame and specified sheet metal subassemblies
We do not design semiconductor process chambers, vacuum systems, hazardous gas delivery, wafer-handling controls or tool-level safety functions. The equipment OEM owns system engineering, risk assessment, cleanliness validation and final compliance; we manufacture and document the released mechanical design.

04 / Manufacturing Process
From Tool Interface Review to Mechanical Assembly
01
Boundary and Datum Review
Confirm the mechanical supply boundary, master datums, module loads, utility zones, service access and controlled documentation.
02
Prototype and Fixture Plan
Build representative frame and panel assemblies, then validate weld sequence, fixture locations and inspection access.
03
Frame Fabrication
Cut, machine, fixture and weld structural members while controlling heat input and critical mounting interfaces.
04
Panel and Tray Production
Form external skins, stainless trays, doors and brackets with material separation and protected cosmetic surfaces.
05
Finish and Mechanical Fit
Apply approved finishes, install specified hardware and verify panel gaps, door operation and module interfaces.
06
Configuration-Controlled Packout
Release the assembly with inspection records and pack components by tool model, revision and installation zone.
05 / Why It Matters
Why Semiconductor Equipment Structures Need Process Discipline
Large fabricated structures must remain accurate after welding and finishing while supporting clean assembly, service access and frequent engineering revisions.
Stable Interface Datums
Process modules align to defined pads and rails, so cosmetic outer surfaces cannot be used as the only inspection reference.
Controlled Contamination
Material segregation, deburring, cleaning and protected packout reduce avoidable residue and cross-contamination.
Assembly-Level Verification
Doors and panels are checked on the production frame because individual part conformity does not guarantee system fit.
Revision Traceability
Tool families change frequently; controlled models, drawings, BOMs and deviations prevent mixed configurations.

Why Equipment OEMs Choose DRAmetal
01
Frame-and-panel DFM
We review the enclosure, frame and internal sheet metal as one tolerance-linked mechanical assembly.
02
Fixture-controlled welding
Weld sequence and locating strategy are built around functional equipment interfaces and inspection access.
03
Mixed-material fabrication
Steel frames, aluminum panels and stainless trays can be managed in one controlled production program.
04
OEM configuration control
Inspection and packout remain tied to tool model, drawing revision and approved change status.

09 / FAQ
Semiconductor Equipment Enclosure FAQ
What parts of semiconductor equipment can DRAmetal manufacture?
We manufacture released mechanical designs such as welded bases, external enclosures, doors, panels, stainless trays, cable supports, brackets and hardware-ready assemblies. Process chambers, vacuum systems, controls and hazardous gas systems remain outside our fabrication scope unless separately defined with qualified partners.
Can you hold frame datums after welding?
Yes, when the drawing defines measurable datums and tolerances. We plan weld sequence, fixtures, machining allowances and inspection around those interfaces. Achievable tolerances depend on frame size, material, weld density and whether post-weld machining is included.
How do you control stainless and carbon-steel parts in one assembly?
The control plan can include material identification, segregated tools and work areas where needed, protected surfaces, approved cleaning, compatible hardware and drawing-defined finish or passivation requirements.
Can assemblies be packed by tool model and revision?
Yes. Parts and hardware can be identified and packed by model, revision, installation zone or assembly sequence, with inspection records linked to the agreed lot or serial traceability.
